If we really could develop in UML, that'd be a nice sweet spot.

But everything I read about the rise and fall of UML is: it's great to start, but never keeps pace with day to day code changes and becomes almost useless out of the gate as real edges force different paradigms.

Now, if you could wake my AI up in the middle of the night and by morning my UML is is perfectly aligned, or the reverse, my UML realigns the code, that'd probably be a sweet deal.

but complexity is hidden in there either way.
